signoff_opt出错

用ICC做后端，run_signoff调用PT与StarRC也没问题。就是到signoff_opt出错。
icc_shell> signoff_opt
Error: This site is not licensed for 'Galaxy-AdvOpt'. (SEC-51)
难道需要更高端的license才能用signoff优化功能么?

联系过synopsys，他们给了这样的回信：

As I further confirmed, starting from ICC 2012.06-XX versions, signoff_opt requires LCA keys, as it is recommended to use the command "focal_opt" instead, and in future the command would be obsolete.

So can you please guide the users to start trying the command "focal_opt" instead.

For more detailed usage information for the command "focal_opt", you can please refer to its man page.

Hope this can help clarify the issue.

看来只能用focal_opt了
